Each of the plurality of the cantilever diaphragms includes a fixed end fixed on the substrate and a free end extending from the fixed end to a position suspended above the cavity. The free end includes a first surface and a second surface oppositely arranged. The free end and the substrate or other free ends are spaced to form a gap. The sound production device further includes a first dielectric elastomer actuator, a second dielectric elastomer actuator, and a flexible connector. The sound production device of the present disclosures adopts dielectric elastomer actuators on both of the upper and lower sides of the cantilever diaphragms to together act on the cantilever diaphragms, thereby improving the linearity of the sound production device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sound production device","description":"A sound production device includes a substrate having a cavity and a plurality of cantilever diaphragms fixed on the substrate.
